JACOB STONE, OF BELVIDERE, NEW JERSEY,-ASSIGNOR TO HIMSELF ANDv AB'RAMF. RANDOLPH, OFWASHINGTON, DISTRICT OF COLUMBIA.

. Letters Patent No. 81,113, dated August 18, 1868.

.- GEATE or RAILROAD-GAR STOVES.

TO ALL' WHOM IT MAY CONCERN: v

r Be it known that I, JACOB STONE, of Bividere, in the county of Warren,and State of New Jersey, have inyentedcertain Improvements in StovesSuitable for Railroad-Cars and I do hereby declare that the following,taken in connection with the drawings which accompanyand form part ofthis specification, is a description of my invention sufficient toenable those skilled in the art topractise it.

The object of my invention is to furnish a stove adapted for use inrailroad-cars, and which, by reason of its peculiarities ofconstruction, will not, in case of accidentsor overturning of the cars,permit any fire to escape from it. i s

Figure 1 is a perspective view,

Figure 2a vertical section, and I Figure 3 a bottom view of a stovemadein accordance with my. invention.

A represents the body of the stove, and which I make of wrought'boiler-iron,and B is an exterior cylinder surrounding the stove, andwhich I prefer to make of Russia iron,

' Between the fire-chamber of the stoveand the top cover, 0, whichcoversat the same time both the inner and outer cylinder, I place a perforatedwrought-iron head or partition, D, and bolt the same securely to theinside of the stove. The perforations are for the purpose of allowing-adraught, but the head is intended to prevent any possibility of escapeof fireor hcated'coals in case of an upset or concussion.

I E and F are two sliding doors nponthe stove, arranged to slide upanddown,but not to swing upon hinges, as customary. These doors are alsoperforated finely, to admit air, and may be bolted securely afterthestove is supplied with fuel, so as not to need to be opened until thecar has stopped at a station.

G represents the grate, which is centrally hinged to an upright post, H,which is supported .in a cross-bar, h, and is made long enough to passdown through the ash-chamber, I, and through the bottom, K, of saidchamher, and upon which it rests and" is sustained, as shown, andbeneath this bottomit is connected with a lever, I, at whose outer endare two sockets, M and N, the former to receive a handle, for thepurpose of agitating and raking the fire, without opening thel'ower doorof the stove, and the latterto receive the same handle, in order I toturn the grate a little farther around, iuforder, to upset thesame whenthegra te is to be emptied, this upsetting b eing caused by bringing aprojection, O, on rim 0, to .coineide with a. notch or opening, P,iii-the grate.

It will. thusbe perceived that, without the need of incurring any riskarising .from accident because-of opening a door to rake, or even tooverturn the whole fire, if need be, the fire in my stove can be managedand regulated without opening any door at all, all cinder-s anddroppingcoals being constantly kept confined beyond all possibility ofescape, except when fresh coal-is to be put in, which need only be donewhen the car is not in motion. g I I g The outer doors, Q R, uponcylinder B, are not made with'perforations, and should be made to fitsnugly. SS are air-inlet holes, near the base of cylinder B, .to admitair into thefspace between the stove and the cylinder, and T Tare sideperforations, near the top of the cylinder, to allow this air, afterbecoming heated by irradiation from the stove, to pass ,out into thecar. i v

i The cover C is so made as to fit snugly upon both cylinders, and coverthem entirely. U is the smokepipe, rising from the centre of this cover.o

Iucase of an overturning of the car, it will now be seen that, even ifthe outer cylinder be torn away by the accident, or the cover '0displaced, or the stove be turned upside down, not a particle of firecan escape from any part of the stove,nor can the stove-cylinder or itshead, D, be fractured, as neither of them are made of castiron orfragile material. i p

The post II confers great strength, in case of accident, by brncirig thegrate at its centre, and thus preventing its fracture under severeshocks. j i

I claim the combination, with a ear-stove grate, of a centralpost,.arranged to be turned in its hearings, and to which the grate iscentrally hinged, substantially as and for the purpose set forth.

I also claim the combination of the grate with the central post,when thelatter extends downwards through the ash-chamber, and beyond its bottomplate, and is supported in the latter, so that the grate may be agitatedor upset, substantially in the manner set forth.
